Question

我无法让猫鼬使用其功能

var boxSchema = new mongoose.Schema({
    identify: String,
    name: String,
    phone: String,
});

var Box = mongoose.model("Box", boxSchema);
Box.create({
    identify: "Foo",
    name: "",
    phone: "",
},(err,box)=>{
    if(err){
        console.log(err);
    }
    else{
        console.log(`box created! ${box}`);
    }
})

似乎有点傻。看起来一切就绪，但是create方法甚至不会触发。一切都从头开始导入

const express = require('express');
const bodyParser = require('body-parser');
const path = require('path');
const mongoose = require('mongoose');
const multer = require('multer');
const GridFsStorage = require('multer-gridfs-storage');
const Grid = require('gridfs-stream');
const methodOverride = require('method-override');

我与数据库的连接是这样完成的：

const mongoURI = 'mongodb://localhost:27017/depo';
const conn = mongoose.createConnection(mongoURI, {
    useNewUrlParser: true,
    useUnifiedTopology: true
});

我也有gridfs存储和multer的实现，但是它似乎与应用程序无关。知道为什么它可能行不通吗？：/

Answer 1

尝试一下：

var boxSchema = new mongoose.Schema({
  identify: {
    type: String
  },
  name: {
    type: String
  },
  phone: {
    type: String
  }
});

var Box = mongoose.model("Box", boxSchema);

var BoxModel = new Box();

BoxModel.identify = "Foo";
BoxModel.name = "";
BoxModel.phone = "";
BoxModel.save();

Answer 2

好吧，我实际上发现了问题。我正在创建此conn对象以使用GridFS，它也不能用作mongodb连接。所以我也必须在附近添加一个mongoose.connect。

mongoose.connect("mongodb://localhost/depo", {
    useNewUrlParser: true,
    useUnifiedTopology: true
});
